The object of this invention is to simplify the device or pen cap attachment, to render the connection of the retaining device on the cap more quickly and. easily accom lished and with greater certainty of immova le attachment, to lessen the number .of the parts comprised in the device, to cheapen the production and to generally render the retainer more advantageous and satisfactory than heretofore.

The invention consists in the combination and arrangement of parts and the construction of certain of the parts all substantially as hereinafter fully described and set forth in the claim.

The improvements are illustrated in the accompanying drawings, in which,

Figure 1 is a side view of a fountain pen with the protecting 'cap thereof in longitudinal section and showing retaining device in place thereon. Fig. 2 is a side view of the cap as constructed in readiness for the attachment thereon of the retainer. Fig. 3, is

4 a perspective view of all of the parts comprised in the retainer shown as in separated relations. Fig. 4 IS a cross sectional view through the cap and retainer on line 4-4, Fig. 1.

Similar characters of reference indicate corrcs onding parts in all of the views.

In t e drawings,A represents the cap for protecting the writing pen a of the fount'ain pen B. The cap has at suitable places between its end transverse rectangular slots b b through its wall at one side thereof.

0 represents the sheet metal stamping comprising a base portion (1 slightly curved I to conform to the cylindrical outer surface of the cap and having integrally formed, rearwardly extending, prongs {f at the upper and lower ends thereof w through said rectangular slots b b andbent or clenched along longitudinal lines against the inner side of the pen ca plate has at the opposite sides of its base integrally formed, forwardly extended ears .9 g with alined perforations h h therethrough.

D represents a sheet metal lever comprising'a finger operating member'i and a hear-- ing member 1' having an angularly turned extremity to bearagainst the side of the cap, and having intermediately thereof opposite perforated ear pieces 7c positioned against the aforementioned forwardly extended ears g g andheld in place by the rivet m, which constitutes the pivot supported by the ear pieces 9 g and on which the retaining lever may be rocked.

The aforementioned base piece is constructed with an integrally formed, struckup, forwardly extended guard tongue a located between said ears, and adjacent, but offset from theline of the perforations and the pivot constituting rivet; and 0 represents a ll-shaped spring, embracing said pivot, having its diver ent members in compression between, an in bearing against, said base plate and the member '5 of said lever, and having its intermediate, return bent, portion engaged, and held against dis placement or becoming lost by said tongue n.

The combination with a cap for a fountain pen having separated transverse rectangular slots through the side Wall thereof, of a sheet metal plate comprising a base ortion conforming to the outer surface of t e cap, having integrally formed, rearwardly extending prongs, at the op osite ends thereof, which are engaged throng said slots and clenched on the inner side of the wall of the pen cap, said late having at its opposite sides integrally ormed, forwardly extended perforated ears, and also having an inte rally formed struck up, forwardly extends guard tongue located between said ears, and adjacent, but
